And a potential prion problem as well. Plants grown in prion-contaminated soil can absorb prions, and animals who subsequently eat the plants can become infected. [1] And while composting might be enough to destroy most infectious diseases, it certainly isn't enough to denature prions. [1] Sandra Pritzkow et al.
